Definitions

  • the invention relates to a packaging bag, in particular a packaging bag made of plastic film, with at least two side walls and a permanently closable or closed filling opening. If the filling opening can be closed, the packaged goods are not yet in the packaging bag. If the filling opening is closed, the packaged goods are already in the packaging bag. The permanently closed filling opening cannot be opened without further ado for the purpose of removing the packaged goods and in any case cannot be closed again after it has been opened.
  • Packaging bags of this type and purpose which have only two side walls, are also referred to as flat bags.
  • the filling opening can be closed by gluing, welding, sewing the side walls, if necessary with an envelope.
  • the packaged goods that are placed on the market in such packaging bags are mostly fine-grained and pourable. It can be relatively small packaging bags, for example for food, feed and. Like., But also act as large packaging bags, for example for cement or chemicals.
  • the packaging bags known from practice, from which the invention is based, it is customary to cut or tear open the packaging bag in whole or in part, mostly in the region of the filling opening, in order to form a removal opening for the purpose of removing the packaging material. For this purpose it is known to install tear strips or tear cords.
  • the packaging bag once cut open or torn, cannot be closed properly again. This is a long-standing issue if packaged goods from the packaging bag are only partially, e.g. B. to be removed in portions one after the other.
  • portion packs which are designed as packaging bags or packaging cushions
  • DE 31 40 018 it is known (DE 31 40 018) to provide a packaging wall with a surface perforation and to cover it with a tear-off film which is torn off in whole or in part in order to fully or partially expose the surface perforation and that z.
  • B. to express pasty packaging over the exposed surface perforation. Resealability is not set up here either.
  • packaging bags with a filling opening which is also a removal opening, this opening being closable and reopening with a profiled strip zipper, usually with a slide.
  • Such packaging bags are not suitable for all uses, because a profile strip zipper is able to absorb only low transverse tensile forces and consequently there is a risk that a packaging bag which is equipped with such a profile strip zipper may become loose after filling the packaging material, e.g. B. in the usual handling until use of the packaging, opens uncontrolled.
  • the invention has for its object to provide a packaging bag of the structure described above, which can be easily opened and closed again for the purpose of portioned removal of the packaging material.
  • the arrangement should be such that the usual technologies for the production of such packaging bags or for the packaging of appropriate packaging goods can be retained.
  • the invention teaches that outside the area of the filling opening on one of the one-piece closed side walls a closure member zipper is arranged in the closed state, the zipper slide on the underside of the slide of which has a separating knife for separating the side wall of the packaging bag arranged under the closure member zipper, and that Sidewall under the fastener zipper by an opening movement of the zipper slide, forming a reclosable emptying opening of the packaging bag, can be separated by the separating knife.
  • the invention takes advantage of the fact that a closure member zipper in the manufacture of packaging bags without Difficulties associated with a side wall of a packaging bag. This is also possible in a simple manner if the packaging bag has already been filled with goods to be packed and the filling opening is closed.
  • the invention uses a closure member zipper, the zipper slide of which is provided on the underside with a separating knife in the manner described, so that when this closure member zipper is opened via the separating knife, a removal opening for the packaged packaged goods is produced by cutting open a side wall of the packaging bag, which is produced with closing the zipper slide can be closed again.
  • the removal opening is thus securely closed, since a fastener zipper has a high transverse tensile strength.
  • zipper sliders with a cutting knife on the underside are known (DE 73 33 589).
  • these zipper sliders are used for sewing-technical reasons in those zippers which are intended for sewing into a piece of clothing.
  • the zippers have straps which are united under the row of fastener elements and which are cut open by the separating knife when the zipper is sewn in. This makes sewing in easier. In this way, the so-called end stop parts can also be dispensed with in such zippers sewn into a garment.
  • the invention teaches that the closure member zipper in the region of the connecting seam and in parallel to be arranged to the connecting seam. This is on the one hand for the assembly of the fastener zipper, but on the other hand it is also particularly easy to handle. The latter applies in particular if, in the embodiment in which the filling opening is used as a connecting seam for the side walls, for. B. is closed as a weld, the fastener zipper is arranged in the area and parallel to the connecting seam of the side walls.
  • the fastener zipper is expediently designed as a very flexible zipper with continuous rows of fastener made from a relatively thin plastic monofilament.
  • the zipper is within the scope of the invention to design the zipper as a gas- and / or liquid-tight zipper. This is important if the packaged packaged goods, after a portion has been removed, are to be packed again gas-tight and / or liquid-tight by closing the removal opening.
  • a preferred embodiment is in the embodiment in which the side walls consist of thermoplastic, characterized in that the fastener zipper has straps made of a thermally weldable plastic with the thermoplastic of the side walls and that the fastener zipper by welding the straps to the associated side wall on the Packaging bags is arranged.
  • the zipper can also be used with the tapes by gluing, sewing and. Like. Be attached to the associated side wall of the packaging bag.
  • the measures according to the invention can always be integrated with the usual technology for the production of packaging bags or for filling such packaging bags.
  • the zipper slide has a fixed separating knife on its underside, which has a cutting edge in the pulling direction and has a support rounding towards the side wall, which prevents the separating knife from piercing the assigned side wall without actuating the slide.
  • a preferred embodiment of the invention is characterized in that the zipper slide has a retractable and extendable cutting knife and this can be operated with the aid of a slide handle. It can be retractable and extendable in the direction of the side wall, which can be achieved with simple mechanical devices.
  • An embodiment which is characterized in this respect by simplicity and functional reliability, is characterized in that the slide handle is L-shaped, the short L-arm being designed as a separating knife, which at the heart of the slide, possibly guided in a groove, frames and the slider handle with the long L-arm is attached to the upper part of the slider in such a way that retraction and extension can be reached in the sense of a swivel movement.
  • the packaging bags shown in the figures may consist of a plastic film and are designed as flat bags with two side walls 1. They have a permanently closable filling opening 2.
  • the packaging bags shown are empty. After the packaging material had been filled in, the filling opening 2 was closed, for example by welding.
  • FIGS. 1 and 2 From a comparative view of FIGS. 1 and 2 it can be seen that the packaging bag outside the area of the filling opening 2 on one of the one-piece closed side walls 1, in the exemplary embodiment on the side wall 1 facing the viewer, has a closure member zipper 3 in the closed state. 3 to 5, you can see. that the slide zipper 4 has on its underside a separating knife 5, which is used to open the side wall 1 of the packaging bag arranged under the fastener zip 3. Apparently, the side wall 1 under the fastener zipper 3 can be separated by an opening movement of the zipper slide 4 by the separating knife 5. In this way, an emptying opening 6 is created for the packaged goods. This emptying opening 6 can be closed again by a reverse movement of the slide slide 4.
  • the fastener zipper 3 is arranged in the region of the connecting seam 7 and parallel to the connecting seam 7.
  • this connecting seam 7 is the seam with which the filling opening 2 was closed.
  • actuation of the slide fastener slide 4 can initially create the emptying opening 6 at the point at which the slide fastener slide 4 was arranged when the slide fastener slide fastener was closed.
  • the emptying opening 6 can be provided with any length by the slide movement, namely up to the full length of the closure member zipper 3. It can always be closed again.
  • the fastener zipper 3 may be a slightly flexible zipper with continuous rows of fastener 8 made of plastic monofilament. It has not been drawn that this closure member zip 3 can also be gas and / or liquid-tight.
  • the side walls 1 of the packaging bag consist of thermoplastic film.
  • the fastener zipper 3 has straps 9 made of a material that can be thermally welded to the thermoplastic plastic of the side walls 1.
  • the fastener zipper 3 is fastened to the packaging bag by welding the carrier tapes 9 to the side walls 1. But it could also be attached by gluing or sewing.
  • the zipper slide 4 has on its underside a fixed separating knife 5 which has a cutting edge 10 in the pulling direction and has a support rounding 11 towards the side wall 1.
  • the zipper slide 4 has a retractable and extendable cutting knife 5 and this can be operated with the aid of a slide handle 12.
  • the slide handle 12 is L-shaped.
  • the short L-arm 13 is designed as a separating knife, which grips the zipper slider 4 on the frog side.
  • the slide handle 12 is attached to the upper part of the slide with the long L-arm 14, with the help of a hinge formation 15 so that the pivoting movement is possible, which results from a comparative view of FIGS. 4 and 5.
